| dc.description.abstract | Pinus scots (Pinus sylvestris L.) merupakan kayu yang banyak digunakan sebagai bahan baku produksi di benua Eropa, namun kayu ini memiliki sifat ketahanan yang rendah terhadap organisme perusak kayu. Modifikasi kimia menggunakan softener dan asam sitrat (2-hydroxy-1,2,3- propanetricarboxylic acid)-sorbitol (CAS) diaplikasikan untuk meningkatkan keawetan kayu. Penelitian ini bertujuan untuk menganalisis pengaruh modifikasi kimia menggunakan softener dan CAS (dengan berbagai rasio molar dan konsentrasi larutan) terhadap keawetan dan keterbasahan kayu pinus scots. Keawetan kayu terhadap rayap diuji melalui pengujian rayap kayu kering dan uji kubur. Pengujian karakteristik permukaan dilakukan sebelum dan sesudah uji kubur. Hasil penelitian menunjukkan bahwa modifikasi kimia mengunakan softener dan CAS meningkatkan ketahanan pinus scots terhadap rayap kayu kering dan rayap tanah. Peningkatan rasio molar dan konsentrasi asam sitrat meningkatkan keawetan kayu. Energi bebas permukaan (SFE) dan keterbasahan menurun setelah perlakuan modifikasi kimia menggunakan softener dan CAS. Kekasaran permukaan, SFE, dan keterbasahan meningkat setelah uji kubur. | id |
| dc.description.abstract | Scots pine (Pinus sylvestris L.) is a wood that widely used as a raw material in Europe, but this wood has low resistance against wood destroying organisms. Chemical modification by softener and citric acid (2-hydroxy-1,2,3-propanetricarboxylic acid)-sorbitol (CAS) was applied to increase the wood durability. This study aimed to analyze the effect of chemical modification by softener and CAS (with various molar ratios and solution concentrations) on the durability and wettability of scotspine wood. The durability of wood against termites was tested by dry-wood termite and grave yard testing. Surface characteristics testing was carried out before and after the graveyard test. The result shows that chemical modification by softener and CAS increased the resistance of scots pine against dry-wood and subterranean termites. The increasing of molar ratio and solution concentration increased the wood durability. The surface free energy (SFE) and wettability decreased after chemical modification treatments by softener and CAS. Surface roughness, SFE, and wettability increased after graveyard test. | id |
